Miscibility of Main Grades

We have tested the compatibility and stability of our Main Grade Range in an independent and ISO 9001 certified Laboratory in Germany. The LUKOIL Navigo product has been mixed with other equivalent products available in the market place at different ratios. The test has been performed at different temperatures and took up to six month. The test results of each grade range are transferable to the entire viscosity- and Base Number (BN) range.
